Final answer:
The patient with a history of insulin-dependent diabetes mellitus and poor visual acuity likely has diabetic retinopathy, a diabetic complication leading to vision issues. Diabetic retinopathy involves damage to the retinal blood vessels, with the potential to progress to vision loss if not managed properly.
Step-by-step explanation:
A 24-year-old patient with a 10-year history of insulin-dependent diabetes mellitus presents with visual acuity of 6/60 in the right eye. Upon examination, the diagnosis for this patient could be diabetic retinopathy, a common complication of diabetes that affects the eyes and can lead to blindness. This condition is characterized by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). Poorly controlled blood sugar is a risk factor for this condition.
Diabetic retinopathy includes several conditions like non-proliferative diabetic retinopathy (NPDR) which is the early stage and proliferative diabetic retinopathy (PDR), which is more advanced and severe. Other conditions such as macular edema can also occur, which is when fluid and protein deposits collect on or under the macula of the eye and can cause swelling.
Regular eye examinations for individuals with diabetes are crucial for early detection and treatment of this and other eye-related complications, potentially preserving vision.
